I don't *know* that all of them are wrong.  Some of them may be genuine
bugs on hppa*-*-hpux*, either with the hp-ux compiler or with gcc
on that target.

Now that I can run the test suite and I can kill lots of them, though.
In fact, I'll go kill some more today.

  % grep -r 'setup_xfail.*hp' ...
